Very good solution for this price, I use it to easily turn powered speakers into Bluetooth receivers. Clearly, the sound quality is not that of a DAC card but it does its job.

When it works, it's just fine, without any delay. But for me, it was losing the connection quite often.

I bought it for use with an old Denon 980r amplifier at the cottage. Quick installation, very satisfactory result. Value for money!

Very worthwhile for its price. The sound quality is clearly not comparable to more expensive systems. I consider it to be decent.
A similar, more makeshift system I had caused humming in the speakers when music or sound transmission generally stopped. This particular product offers smooth operation, so far, at a 25m distance in the house with closed doors in between and brick walls.
For better performance, use a cable suitable for Hi-Res Audio.
I highly recommend it.

This gadget is awesome, zero lag, no ifs or buts. It does its job and then some. The higher the quality of the audio reference system, the better the result. Worth it.

Very good solution to turn your old hi-fi system (or anything else you want) into bluetooth. We used it at a birthday party and it worked perfectly!

Excellent product for this price! Easy connection, good sound quality, very good range!

I got it to add Bluetooth functionality to a Tivoli One radio, an old model. It works flawlessly with iPhone 12. Excellent!

Very good device with excellent preamplification. The quality is truly incredible, and it easily connects even with two devices simultaneously. Now for the negatives (which is why 4 stars): the Bluetooth version it has is old and there is a slight delay with some occasional interruptions, but this is not such a big problem. The only thing that bothers me is that it doesn't have an on/off switch and plugging and unplugging it is a bit tiring. Other than that, it's a very good little gadget and I recommend it.

I use it to connect to an old amplifier. It connects easily and without problems. Average sound quality and the volume is low. No comparison with the sound quality and output of the CD player.. it simply does the job it was made for.....

It works very well. Immediate connection with the devices and the process of syncing the devices is very simple.

Usage for connecting smartphone (spotify, google music) to existing sound system. No issues with the range even when I move to the next room. I don't notice latency issues with YouTube videos, although I haven't used it with a movie. Small sleek size with double-sided tape you can mount it wherever you want.

Amazing.
Super easy to connect. Watch videos on YouTube, because the instructions can confuse you.
Crystal clear sound. Maybe a little less powerful, but it depends on the source. The Home Cinema I have is from 2010.

Easy to use, does what it promises. I connected it to an analog amplifier - speakers, distance about 12 m. Use with mobile, PC.

Excellent in every way.
Ease of connection.
Several input options.
No USB power supply, only from the socket.

simply perfect but the new model only supports 2 devices compared to the old one which was for 8! but it definitely worth the money for old hiking, TVs etc. that do not have BT connection

I have connected it to a Denon AVR amplifier for playback from my phone/computer. It connects perfectly and plays without any problems

It does a very good job, I have it in my home cinema from the computer to watch movies or listen to music from the computer, you save the trouble with cables how to pass them and in what way, etc.

Excellent! Very good connection, simple and fast installation. The only comment, for those who are interested, is that it takes up an extra socket compared to having speakers with built-in Bluetooth.

I received it on 15/3/2024 and within half a minute I had it connected. I have a new amplifier and I was scared when they told me not to connect it directly to the computer because it can cause damage to the amplifier's components at high volumes. Asking around, I found this magical little box and I calmed down. I really don't hesitate to give it a little volume now. It's worth its money and more. I have it two meters away from the computer and it's perfect.

Really excellent little gadget, works perfectly from the first use!
It has very good sound quality.
It was tested with a Denon amplifier and B&W speakers.
Worthy of a good hi-fi sound system

Very good, it connects easily. I plugged it into the AUX of my old amplifier with an extra RCA to RCA cable that is not included in the package, and the response is perfect. I have only tested it with music from my mobile phone.

I had a SONY stereo which, although very good, was getting old and did not support wifi. This little thing saved me! Affordable, easy to install, and with a very good range. Simply perfect!

Excellent tool. Beautiful construction and it seems to be of high quality!
I connected my smart TV to Logitech's 5.1 speakers, which didn't have Bluetooth or optical or HDMI ARC input. They connected to each other in a second and the most important thing is that the sound quality is impeccable.

It works exactly as you expect it to work without any problems. The range is smaller than that of the airpods, but that doesn't mean it is small.

I connected it to the amplifier and now I can listen to music through the laptop or mobile with better sound quality. I listened to the same song through an original CD from the laptop's CD player and YouTube without any noticeable difference. The sound from a decent CD player connected to the amplifier is clearly better, as mentioned in the reviews, but you sacrifice quality for convenience (no need to insert and remove CDs).

It receives power through the amplifier, so when I turn on the amplifier, it automatically turns on and connects to the last device that was connected to it, for example, on the laptop, the sound is sent to the Logitech instead of the laptop's speakers, without any intervention from me. The connection is stable without any interruptions (the Logitech is in direct line of sight with the laptop). The only downside is that when I stop playback, a small scratch sound is heard.

I think I bought it in 2017. Apart from 1-2 times all these years, when it needed reconnection (and it wasn't exactly its fault, but my TV's), it works non-stop. It gives my old stereo (an Aiwa from 1998) BT connectivity and works perfectly with the TV.
It does exactly what I bought it for, very well, for many years.

EDIT: Successfully connected to a new TV (even easier and faster - a sign of how bad my old TV was :p ). It continues to work without any problem and does what it promises.
For the record, I bought it for €24.
EDIT2: 4 years later, and in a total of 9 years of use, this product still works flawlessly, for anyone still interested in something similar, keep it in mind :)

"The device automatically reconnects when it is within range. This is also its main problem if you want to use it with a mobile phone and transfer the sound to an external source. Basically, whenever you enter the area where the device is located, it automatically connects to the mobile phone. If you go to the Bluetooth settings of the mobile phone and disconnect... it reconnects in 10 seconds. It is hardware with sadistic character. The only solution is to disconnect it from the power since it does not have an ON/OFF button. However, it is honest, it tells you before you buy it. Otherwise, the RCA connections are essential and it transfers the sound as it should.

In conclusion, if you find a device that has the option to disconnect and a power button, prefer it (if it exists, I didn't search). This particular one can drive you crazy if it catches you on a bad day."

After a few months of use, my experience with this specific product is flawless. It does what it's supposed to without freezing, without delay, without any issues whatsoever. It's worth it and more! I have connected speakers and as soon as I turn on Bluetooth on my device, it automatically connects straight away.

Very convenient and does what it promises. It includes a charger as well as a 3.5mm jack to RCA cable. I have connected it to my logitec z906 to be able to play music from my tablet or mobile through apps like YouTube, Spotify, Tidal, etc. I have no issues with interruptions or playback. Obviously, we are talking about a good gadget that makes your speakers Bluetooth-enabled at a low price. If you want hi-fi, go for a much more expensive solution with ten times the price, which obviously doesn't make sense because all the new quality streamers have Bluetooth capabilities.
